Frequently Asked Questions

What are the differences between American and European standard pulleys?

American standard pulleys follow ANSI/RMA specifications (IP-20, IP-22, IP-23), while European standards comply with ISO 4183 and GB/T 10412. Dimensions, groove profiles, and naming conventions differ between the two systems.

How do I choose the right V-belt pulley?

Consider the belt type (SPA, SPB, 3V, 5V, etc.), shaft diameter, speed ratio, horsepower, and operating environment. Ensure compatibility with your existing system and adherence to regional standards.

What materials are used in your pulleys?

We primarily use G3000 grade cast iron for its excellent strength, wear resistance, and vibration damping properties. All pulleys undergo black phosphating for enhanced corrosion resistance.
